Originally developed for mobile Augmented Reality (mAR), PEARL was adapted for MR to offer a more immersive and intuitive experience through hand and gesture controls. Since many students lack experience with MR devices, a user-friendly onboarding system is essential. The study aims to redesign PEARL’s user interface and onboarding experience, evaluating how intuitive interaction elements impact usability. First, a literature review will identify existing usability guidelines for MR applications, which will guide the redesign of the interface. This new version will then be tested with students through a user study. Feedback will be collected via an online survey to assess the onboarding and user experience, and the findings will be used to refine the design further. The expected outcome is an improved onboarding process and interface, making PEARL accessible even for MR novices, enhancing their ability to interact with 3D objects in a real-world setting. Ultimately, the study aims to provide best practices for developing intuitive MR interfaces and effective onboarding experiences, especially in educational contexts."}],"publication":"Lecture Notes in Networks and Systems","language":[{"iso":"eng"}],"keyword":["Meta Quest 3","Augmented Reality","Mixed Reality","PEARL","Electrical Engineering","Laboratory Training","Onboarding","User Experience","User Interface","Heuristics"]},{"date_updated":"2026-04-29T11:15:43Z","author":[{"full_name":"Rosenkranz, A.

Possible architectures of PONyDAC are derived and compared in terms of performance and practicability. Moreover, the limits of PONyDAC systems and their superiority over classical electronic DACs are discussed. Furthermore, discrete building-block based implementations and monolithic implementations in electronic-photonic integrated circuits (EPICs) are presented. To enable a practicable monolithic integration, a shrinkage of the Mach-Zehnder modulators (MZMs) has been performed by applying forward-biased phase shifters (FB-PSs). These FB-PSs are analyzed and modeled to allow the precise and reliable design of PONyDAC systems with multiple MZMs. Finally, data conversion and data transmission experiments are carried out to demonstrate the systems functionality, quantify its performance, and prove their superiority over purely electronic DACs.</jats:p>"}],"type":"book_chapter","publication":"Electronic-Photonic Integrated Systems for Ultrafast Signal Processing","language":[{"iso":"eng"}],"user_id":"13256","department":[{"_id":"58"},{"_id":"623"}],"_id":"65518","citation":{"apa":"Scheytt, J.

In this work, we initiate the study of verification of classical shadows,\r\ndenoted classical shadow validity (CSV), from the perspective of computational\r\ncomplexity, which asks: Given a classical shadow S, how hard is it to verify\r\nthat S predicts the measurement statistics of a quantum state? We show that\r\neven for the elegantly simple classical shadow protocol of [Huang, Kueng,\r\nPreskill, Nature Physics 2020] utilizing local Clifford measurements, CSV is\r\nQMA-complete. This hardness continues to hold for the high-dimensional\r\nextension of said protocol due to [Mao, Yi, and Zhu, PRL 2025].

This process can be viewed as performing hundreds of parallel reactions programmed on a self‐assembled nanoscale platform. While previous studies have focused on investigating the collective results of the chemical or enzymatic ligation reactions, herein, the global quantitative analysis of individual ligation reactions is achieved using quantitative PCR (qPCR). By mapping enzymatic ligation efficiency on a trapezoidal substructure representing one‐third of a triangular DON, ligation is shown to preferentially occur at the trapezoid edges rather than at inner sites. Excellent agreement between the experimental ligation yields and docking simulations suggests that this is a result of variations in the ligase docking probability. Ligation products involving more than two consecutive sequences can be generated with each enzyme‐catalyzed reaction as an independent event. Interestingly, the sharp contrast between the edges vs. the inner sites has been abolished by changing the reaction conditions and performing the ligation in a DMSO co‐solvent system. This analytic method provides unprecedented insight into the multiple ligation reactions occurring in parallel within complex DONs and will be an invaluable tool in the translation of DONs from the lab to real‐world applications.</jats:p>","lang":"eng"}]},{"page":"18","citation":{"apa":"Knauff, M., Butz, M.

Based on this, our findings indicate four actions that impact a successful process mining project and the underlying dynamics. (1) Two development phases in a test and productive environment can lead to data driven process improvements. (2) Maintenance and the associated technical debt can cause process drift. (3) Scope creep of the project is easily identifiable in such logs and hinders the complete process mining initiative and (4) a sufficient user base and constant interaction with allows for bottom up process change. These results provide quantitative insights into the development and adoption cycles of the software and the direct impact on the processes as well as the business process management initiative. From this initial analysis researchers can benefit from first insights into the quantitative side of a process mining project and our categorization of the findings.

Besides insights from business process management, software development knowledge like systems interaction and network knowledge is required. For a well functioning process automation these different skill sets must be combined. In a design science research study, concepts from business process management, software development, and best practices are combined to design an actionable development method for RPA. The resulting PM2RPA method structures the development process in four stages: pre-Development, design, development and operations. Within these four stages, 14 activities support product owners, developers, and process experts over the course of the development process. The PM2RPA Method is demonstrated in an environment characterized by frequently changing business processes and heavy resource restrictions due to a lack of skilled workers. The PM2RPA method allows process-driven development while focusing on systems integration and reporting, resulting in a structured and comprehensive method for developing RPA bots. Practitioners can use this method to manage their automation projects. At the same time, researchers benefit from a baseline method aiming to address methodological research challenges and early insights into wider operational strategies for RPA.","lang":"eng"}],"editor":[{"last_name":"van de Weerd","full_name":"van de Weerd, Inge","first_name":"Inge"},{"first_name":"Bedilia","full_name":"Estrada Torres, Bedilia","last_name":"Estrada Torres"},{"last_name":"van der Aa","full_name":"van der Aa, Han","first_name":"Han"}],"user_id":"92908","_id":"65548","language":[{"iso":"eng"}]},{"publisher":"Hogrefe","date_updated":"2026-05-04T09:29:16Z","date_created":"2026-05-04T09:29:08Z","author":[{"last_name":"Grimminger-Seidensticker","full_name":"Grimminger-Seidensticker, Elke","id":"85816","first_name":"Elke"},{"first_name":"Felix","last_name":"Ehrlenspiel","full_name":"Ehrlenspiel, Felix"},{"full_name":"Hepperle, Lisa","last_name":"Hepperle","first_name":"Lisa"}],"title":"Negative Emotionen im Sportunterricht","publication_status":"published","place":"Göttingen","year":"2026","citation":{"chicago":"Grimminger-Seidensticker, Elke, Felix Ehrlenspiel, and Lisa Hepperle. “Negative Emotionen im Sportunterricht.” In <i>Schulsport.

The association of socio-economic status, gender, or the home language was consistent with prior findings, predictors related to learning processes, however, vary across educational contexts.\r\n                  </jats:p>\r\n                  <jats:p>\r\n                    <jats:italic toggle=\"yes\">Discussion</jats:italic>\r\n                    . Our results demonstrate that ICILS 2023 items can be mapped onto multiple established CT frameworks, supporting their broader validity and utility for comparative research. The findings of the regression analysis underscore the complex interplay of non-cognitive factors affecting CT and illustrate the significance of contextual interpretation within educational systems.\r\n                  </jats:p>"}],"status":"public","publication":"ACM Transactions on Computing Education","type":"journal_article","title":"Computational Thinking in ICILS 2023: Analyzing the Construct and Its Antecedent- and Process-Level Predictors","doi":"10.1145/3813115","date_updated":"2026-05-05T08:28:21Z","publisher":"Association for Computing Machinery (ACM)","author":[{"last_name":"Vahrenhold","full_name":"Vahrenhold, Jan","first_name":"Jan"},{"first_name":"Jan","id":"32467","full_name":"Niemann, Jan","last_name":"Niemann"},{"full_name":"Drossel, Kerstin","id":"48921","last_name":"Drossel","first_name":"Kerstin"}],"date_created":"2026-05-05T08:25:52Z","year":"2026","citation":{"ieee":"J.
